[文档]class Interval(HyperCube):
r"""
Definition of Interval object.
Args:
name (str): name of the interval.
coord_min (Union[int, float]): left of the interval.
coord_max (Union[int, float]): right of the interval.
dtype (numpy.dtype): Data type of sampled point data type. Default: numpy.float32.
sampling_config (SamplingConfig): sampling configuration. Default: None.
Raises:
ValueError: If `coord_min` or `coord_max` is neither int nor float .
Supported Platforms:
``Ascend`` ``GPU``
Examples:
>>> from mindflow.geometry import generate_sampling_config, Interval
>>> line_config = dict({'domain': dict({'random_sampling': True, 'size': 100, 'sampler': 'uniform'}),
... 'BC': dict({'random_sampling': True, 'size': 10, 'sampler': 'uniform',}),})
>>> line = Interval("line", -1.0, 1.0, sampling_config=generate_sampling_config(line_config))
>>> domain = line.sampling(geom_type="domain")
>>> bc = line.sampling(geom_type="BC")
>>> print(bc.shape)
